“…In line with other studies (Campbell et al, 1993;López-Bellido et al, 2012), a strong influence of climate was observed due to the particular high variability of rain during the growing season in the Mediterranean climate. The change in conditions caused the variations in physiological responses of the crop, grain yield and N efficiency.…”

“…Nitrogen also leads to higher photosynthetic activity and canopy development, as shown by the SPAD and LAI values. This confirms the importance of N on the cultivation in different conditions typical of the Mediterranean climate (Ercoli et al, 2009;López-Bellido et al, 2012). The increase in application favoured an increase in yield in all cases in the three years, due to the higher average rain registered during the experiments.…”

“…Splitting the amount of N fertiliser also increases the efficiency of nitrogen use efficiency, with a higher plant recovery of this mineral and an increase in grain yield and quality, compared to a single application (López-Bellido et al, 2012).…”

Optimising nitrogen in order to improve the efficiency, eco-physiology, yield and quality on one cultivar of durum wheat

et al. 2014

A 3-year field experiment was carried out in southern Italy to evaluate the effect of different combinations of nitrogen (N) fertiliser rates (0, 55, 90, 135 kg ha -1 ), time of application (sowing, tillering, stem elongation) and number of nitrogen applications on durum wheat (Triticum turgidum L., var. durum). A total of eight different combinations -in terms of quantity and time of application -were arranged in a randomized complete block design with four replications. Soil plant analysis development was analysed along with leaf area index, grain and straw yield, plant height, plant lodging, thousand-kernel weight, non-vitreous kernels, shrunken and discarded kernels, hectolitre weight, grain protein content, and sodium dodecylsulfate sedimentation. Nitrogen contents of soil, grain and straw were measured in order to assess nitrogen efficiency. The results showed the positive effect of increased nitrogen dosages of 90 and 135 kg ha -1 . The optimisation of nitrogen administration increased by splitting the nitrogen into three application times, as shown by the eco-physiological, productive and qualitative parameters, and the nitrogen efficiency parameters measured (N application efficiency and N recovery fraction).

“…At the three levels of N fertilization both grain yield and grain N content were maintained under NT conditions compared to CT irrespective of the presence of cc. In a number of studies, it has been shown that in wheat, NT or reduced tillage can in some cases lead to an increase in grain yield in comparison to conventional agricultural systems [33][34][35][36]. In contrast, Machado et al [37] found that over six years, the yield of spring wheat was on average 21% lower in NT soils, thus indicating that the impact of NT on grain production largely depends on the environmental conditions and on the experimental set up.…”

Investigating the Combined Effect of Tillage, Nitrogen Fertilization and Cover Crops on Nitrogen Use Efficiency in Winter Wheat

et al. 2017

A field study was conducted in northern France over two consecutive years to evaluate the combined effect of conventional tillage (CT) vs no till (NT) with or without cover crops (cc) and nitrogen (N) fertilization on various agronomic traits related to N use efficiency in winter wheat. Five years after conversion of CT to NT, significant increases in N use efficiency, N utilization efficiency, N agronomic efficiency, N partial factor productivity, N apparent recovery fraction and N remobilization were observed under three N fertilization regimes (0, 161, 215 kg ha −1 ). It was also observed that grain yield and grain N content were similar under CT and NT. The N nutrition index was higher under NT at the three rates of N fertilization. Moreover, N use efficiency related traits were increased in the presence of cc both under NT and CT. Thus, agronomic practices based on continuous NT in the presence of cc, appear to be promising strategies to increase N use efficiency in wheat, while reducing both the use and the loss of N-based fertilizers.

“…According to Peltonen-Sainio and Peltonen (1994) under favourable conditions N application alone in spring may be sufficient to promote plant growth, but may result in insufficient N availability during grain filling. For this reason the splitting of the nitrogen application rate is recommended for an efficient use of fertilizer-N (López-Bellido et al 2012). Nevertheless in the last years an increasing diffuse nitrate loading of surface water and groundwater has emerged as a major problem in many agricultural areas of the world, resulting in contamination of drinking water resources (Sebilo et al 2013).…”

Ammonium fixation and release by clay minerals as influenced by potassium

2014

It is postulated that stabilized ammonium fertilizers improve fertilizer-N utilization by crops, leading thus to higher yields with the same fertilizer rate, especially on sandy soils. However, it must be taken into consideration that in clayey soil at least a part of the NH 4 + ions may be fixed by 2:1 clay minerals, thus delaying the effect of the N fertilizer. Because NH 4 + and K + have similar size and valence properties and therefore compete for the same non-exchangeable sites of 2:1 clay minerals, we investigated the influence of time and K + application rate on both fixation and release of NH 4 + . Fixation of NH 4 + ions was higher when K + was applied after NH 4 + , while the influence of the K + application rate was less pronounced. Mobilization of non-exchangeable NH 4 + was retarded when K + was applied at the high rate after NH 4 + . At the first harvest yield formation of ryegrass was neither influenced by the amount as well as the application time of K + , because plant available N was not growth limiting, while yield of the second harvest was significantly higher with the low K + application rate after NH 4 + . After the second harvest the blocking effect of K + on the release of non-exchangeable NH 4 + was attenuated and the highest yields of the third cut were reached in the treatments with the high K + application rate after NH 4 + . Total dry matter yield was highest when K + was applied at the low rate after NH 4 + . Our results show that K + governs fixation and release of non-exchangeable NH 4 + , which should be taken into consideration when applying ammonium containing N fertilizers like ammonium sulfate, ammonium sulfate nitrate and ENTEC. Thus K + can affect N availability when N is applied as NH 4 + in both the short and long term.
